iGCSE Of Mice and Men Character ComparisonsWatch

I've got my mocks in two weeks and for my English lit I'll be getting an essay on of Mice and Men. The exam gives us a character question.We'll either get one character or two to compare/talk about simultaneously. Any examples of characters they would pair?

So far I've got Candy, Crooks and Curley's Wife all pairing together on loneliness and neglect. I've also got Slim and Curley together on authority/hierarchy. Any other ideas? I'm not sure who Lennie and George would be paired with, perhaps each other on friendship/ranch life? Thanks in advance!
